MEAT-INSPECTION TABLE on. SUPPORT.

Specification of Letters Patent.

Patented Mar. 9, 1920.

Application filed February 24, 1919. Serial No. 278,966. 7

tain new and useful Improvements in Meat- Inspection Tables or Supports; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a table for supporting meats whereby theymay be thoroughly sterilized and inspected, and an object of the present invention is toprovide a table of this character which may be, readily and easily cleaned after being used.

and one which can be readily and quickly heated or cooled as occasion may require.

With the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been shown a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which recourse may be had that come within the scope of the claims without departing from the spirit of the invention or sacrificing the efficiency of the same.

In the accompanying drawings;

Figure 1 is a perspective view of the table embodying the present invention;

Fig. 2 is a detail vertical section through the same on line 22 of Fig. 1;

Fig. 3 is a vertical section through the outlet exhaust valve; and,

Fig. 1 is a detail horizontal section through the same on line of Fig. 3.

Referring now more particularly to the accompanying drawings wherein like and corresponding parts are designated by similar reference characters throughout the several views.

In the drawings we have disclosed a table comprising a supported slab 1 which is supperature of the slab 1. this slab 1 is a bell-shaped sprayer 21 which ported by means of the legs 2 and these legs 2 are reinforced by means of the stay rods 3. Whereas we have shown and described supporting legs 2 for holding this slab 1, it is of course to be understood that the slab may be mounted in any other manner such as upon a truck so that it may be transported from place to place. This slab, 1 is formed or cast as a single piece of metal having a rectangular'configuratlon and having upper and lower walls 1 and 5 respectively, end

walls G and side walls 7, thereby forminga chamb'erS therein. Leading tothis chamber 8 are the inlet pipes 9 which have a controlling valve 10 arranged therein whereby steam or any other heating medium may be carried to this chamber 8. One of these inlet pipes 9 may have in communication therewith an auxiliary valve controlled pipe 11 whereby compressed air may enter the chamber 8 for blowing out the steam or any other heating medium contained therein.

Leading from this chamber 8 at one corner within the chamber 8 this valve 15 will be opened so as to permit the steam to exhaust from the chamber 8 and out through the pipe 18, connected to the outer end of coupling 13.

A steam gage 19 is also in communication with the chamber 8 and a thermometer 20 is provided for readily indicating the tem' Arranged above is supported by the hot and cold water supply pipes 22 whereby either hot or cold water may be sprayed upon the upper face of the slab 1 for cleansing the same.

In the drawings we have illustrated two supply pipes 9 for supplying steam within the chamber 8 and these supply pipes 9 are arranged at the alternate ends of the slab 1. This is done so that the steam or other heating medium may be ouickly and read ly supplied to the chamber 8 for quickly raising the temperature of the slab 1. The meat to be inspected is placed upon the top of the slab 1 and the heat from this slab which is a dry heat will readily kill any germs that may be within the meat. When the meat is removed from the slab it is desired that the same be thoroughly clean and sterilized. In cleaning this slab l the hot and cold water may be supplied thereto through the spraying nozzle 21, and when it is desired a dome-shaped cover may be placed over the slab 1 so as to retain the heat above the slab, whereby the slab will be thoroughly sterilized after having been cleaned. When it is desired to remove the steam or heating medium from the slab l the valves 10 may be closed and the valve arranged within the pipe 11 opened so that compressed air may flow through this slab for driving the heating medium through the pipe 12.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is 1. In a meat inspection table of the charspecified.

porting said slab, a plurality of inlet pipes leading to said chamber for supplying a heating medium thereto, a compressed air pipe communicating with one of said supply pipes, and an outlet pipe leading from said chamber.

2. In a meat inspection table of the character described, comprising a hollow slab formed with a chamber, supports for said slab, inlet pipes disposed at the opposite ends of said slab and communicating with said chamber for'supplying a heating medium thereto, a pipe connected to one of said heat supply pipes and adapted for the passage of air under pressure for ejecting the heating medium from said chamber, an

outlet pipe leading from said chamber, and asprmgb valve arranged within said outlet pipe, su stantially as and for the purpose In witness whereof we have hereunto set our hands.
